How to find experimental probability?

Answer

Experimental probability is found by conducting an experiment and recording the results. Here's how to calculate it:

Formula: $\text{Experimental Probability}=\frac{\text{Number of times an event occurs}}{\text{Total number of trials}}$

Steps:

1. Conduct your experiment - Perform the action multiple times (flip a coin, roll a die, etc.)
2. Record all outcomes - Keep track of every result
3. Count favorable outcomes - Tally how many times your specific event happened
4. Count total trials - Add up all attempts
5. Divide - Use the formula above

Example: If you flip a coin 50 times and get heads 23 times:

• Experimental probability of heads = $\frac{23}{50}=0.46\text{or}46\mathrm{\%}$

Key points:

• The more trials you conduct, the closer experimental probability usually gets to theoretical probability
• Results vary each time you repeat the experiment
• It's based on actual results, not what "should" happen mathematically

This differs from theoretical probability, which is calculated mathematically (like knowing a fair coin has a $\frac{1}{2}$ chance of heads without flipping it).
